Description

TECHNICAL FIELD

[0001] The full-automatic slicing device for brazing copper foil belongs to the technical field of mechanical processing production. BACKGROUND

[0002] Brazing refers to a welding method that uses liquid filler metal to fill the gap of solid workpieces to connect metals after the filler metal and the workpiece are heated to the filler metal melting temperature, which is lower than the melting point of the workpiece. Brazing has been applied to various mechanical production methods. For example, in the production of flow distribution plates, due to the complex design of some special flow distribution plate channels, the channels cannot be directly machined, and the channels are directly formed during casting. This not only has high process difficulty, but also cannot guarantee precision. Therefore, a multi-layer metal plate stacking and brazing method is considered for production. Such a production method requires covering copper foil between adjacent metal plates for high-temperature brazing to perfectly fuse the multi-layer metal plates without gaps. However, such a brazing method requires determining the amount of copper foil, which often requires a small thickness of copper foil. In addition, flow distribution plate manufacturers need to customize the size of the copper foil according to the actual production needs of the accessories, and the production demand of a single product is not large, which increases the cost of customization and purchase. Therefore, a low-cost machine for independently punching copper foil is needed for small-batch customized production of copper foil punching. SUMMARY

[0037] The collecting box 8 is placed with a stable block, and a collecting vertical pin is vertically arranged on the stable block. Since the flow distribution disc has a center hole, the cut brazing copper foil has a center hole, and when the size is designed, the width of the conveying belt 51 only needs to be slightly larger than the diameter of the brazing copper foil, so that the brazing copper foil can be just sleeved on the collecting vertical pin when falling on the conveying belt 51 and falling at the output end.

[0038] Working process:

[0039] The suitable customized upper punch 45 and lower punch 46 are respectively installed on the movable block 44 and the third base 41, and various parameters of the utility model are set.

[0040] The copper foil roll is sleeved on the feeding shaft 24 of the feeding mechanism 2, the material blocking frame 23 is sleeved on the feeding shaft 24, the copper foil roll is pressed on the material bearing disc 22, so that the copper foil roll can rotate with the feeding shaft 24, a certain length of copper foil belt is placed, the end of the copper foil belt is flatly inserted through the gap between the upper roller group 32 and the lower roller group 33, and then placed on the lower punch 46 of the blanking machine 4, and the pressure shaft of the trigger discharging mechanism 7 is placed on the copper foil belt between the feeding mechanism 2 and the feeding mechanism 3.

[0041] The power device 43 of the punching machine 4 controls the movable block 44 to rapidly descend and then ascend, the upper punch 45 and the lower punch 46 are rapidly combined to realize rapid slicing of the copper foil strip, then the high-pressure air nozzle sprays air flow onto the upper surface of the lower punch 46, the brazing copper foil and the residual piece cut and sliced are blown onto the conveying belt 51, the cover 52 can prevent the brazing copper foil from being blown to the outside, and under the blocking effect of the two sides and the top, the brazing copper foil can also be slowly adjusted to the middle of the conveying belt 51 during the transportation process, when reaching the output end of the conveying belt 51, the brazing copper foil falls into the collecting box, and since the brazing copper foil has a hole in the center, the brazing copper foil can be just sleeved on the collecting vertical pin when falling, so that the work of collecting and arranging of the staff is reduced.

[0042] After the punching machine 4 completes one-time cutting, under the feedback of the system, the feeding motor rotates a certain number of revolutions according to the setting, drives the upper roller group 32 and the lower roller group 33 to rotate in opposite directions, and simultaneously sends the copper foil strip clamped in the gap downward to the lower punch 46 by a certain length (the copper foil is ductile, so that the front end of the copper foil can be moved forward by the pushing force applied from the rear), after the conveying is completed, the punching machine 4 continues to implement the slicing work;

[0043] When the feeding and slicing are performed for multiple times, the copper foil strip between the feeding mechanism 2 and the feeding mechanism 3 gradually decreases, the copper foil strip will trigger the pressure shaft of the discharging mechanism 7 to be upwardly supported, so that the movable rod 71 rotates around the hinge point thereof, until the trigger rod 73 touches one of the contact sensors 74, the contact sensor 74 sends a “lack of material” signal to the system, then the feeding motor of the feeding mechanism 2 is started to drive the feeding shaft 24 and the copper foil roll to rotate and discharge, the pressure shaft of the discharging mechanism 7 presses the copper foil strip during the discharging process, under the action of the counterweight rod 72, the movable rod 71 rotates downwardly with the copper foil strip descending, until the trigger rod 73 touches the other contact sensor 74, the contact sensor 74 sends a “material sufficient” signal to the system, then the feeding motor of the feeding mechanism 2 is stopped.
